Calendar app help!

Hi everyone. First off I know the title sounds kinda dumb, after all the calendar app is pretty straight forward, right?
Well, what I am trying to do (and failing miserably as of right now) is export the calendar I've got on my touch to a single file that can be manipulated. Say ics, csv,...
Basically what I'm trying to do is extract all my appointments from my Ipod Touch 2G and sync them with google calendars. Does anyone know how to do this? Apparently whenever I sync my iPod the appointments I've on Outlook end up on the iPod, but not the other way around: if I add on appointment on my iPod and sync it with iTunes it will not appear in my Outlook calendar. I suppose this is normal, so is there any way to extract the calendar?
